For the past 2 weeks I have been getting calls from a company claiming to register companies for voice search optimization. I've repeatedly told them to stop calling me, to which they respond that the calls won't relent until I sign up with their service. I've been threatened, mocked, and just straight hung up on, so now I enjoy just waisting as much of their time as possible. I filed a complaint last week, so I'm just logging all their calls to increase the inevitable fine (they're US based, all of the agents are clearly American).
